Application filed March 31, 1917. Serial No. 158,926.

(GRANTED UNDER THE PROVISIONS OF THE ACT GF MARCH 3, 1921, 41 STAT. L, 1313.)

TooZZ whom it may concern:

Be it known that we, JOHN NEWTON HARDY, HARRY D. lVILsoN, and DAVID S. LONG, citizens of the United States, residing at TVaycross, in the county of WVare and State of Georgia, have invented certain new and useful Improvements in HotWVater Radiators, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to radiators for heating purposes, and particularly to hot water radiators.

The general object of the invention is the provision of a very simple and cheaply constructed hot water radiator.

A further object of the invention is to construct the radiator in sections, which may be easily assembled to form a radiator of any desired number of coils.

Other objects will appear in the course of the following description.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a vertical sectional longitudinal view through a radiator constructed in accordance with our invention;

Fig. 2 is a vertical sectional view of the top coil;

Fig. 3 is a vertical sectional view of a middle coil;

Fig. 4 is a vertical sectional view of the bottom coil.

Referring to these drawings, it will be seen that our improved radiator consists of a plurality of coils superimposed on'each other and engaged with each other by means which will be hereafter stated, the uppermost coil, which is designated 10, having connected thereto a hot water inlet pipe 11, which ex ends downward within the several coils, nearly to the bottom of the radiator, and there is connected by a coupling 12 to the upwardly extending stem 13 of two conjoined heating chambers 14 and 15. Each of these heating chambers is flat on the bottom and has upwardly and centrally inclined top walls, the lowermost chamber 15 being connected to the uppermost chamber by means of a neck 16. Though we have illustrated two chambers. it is obvious that more or less than two chambers might be used. The lowermost heating chamber 15 is disposed adjacent the bottom of the lowermost coil and disposed below this relatively large heating chamber 15 is a gas burner 17 of any suitable construction having a gas inlet pipe 18. Connected to the chamber 15 by a T159 and a branch pipe 20 is a water inlet plpe 21, provided with a valve for controlling the inlet of water and connected to any suitable source of water supply. The gas pipe 18 is, of course, provided with a valve controlling the supply of gas to the burner. This T 19 is connected by a branch to the lowermost coil 22 of the radiator. The water which is delivered to the heating chamber 15 moves upward through the pipe 11 in the: direction of the arrows in Fig. 1 into the uppermost coil 10, travels around this coil to the opposite end of the radiator, then downward to the next adjacent coil and around this coil and down into the next adjacent coil and so on through the several coils until it eventually arrives at the coil 22 and is discharged by the T 19 and branch 20 into the heating chamber 15 to again circulate through the several coils.

While we do not wish to be limited, generally speaking, to any specific construction for the several coils, we have illustrated the construction which has been found to be particularly good in practice. The radiator is formed, as before stated, of a plurality of coil sections which are engaged with each other to form the complete radiator. There is a top section 10 and a bottom section 22, which is formed like the top section, except that it is not inverted and there are a plurality of intermediate sections 23 and 2 1. The top section 10 is illustrated as being substantially elliptical in section and as having at its opposite ends the downwardly extending necks 25, the lower ends of these necks being reduced in diameter, as at 26. The bottom section 22 is formed at opposite ends with upwardly extending necks 27, these necks being cut away on their inside faces as at 28 and one of the necks being provided with the integral' transverse wall 29, as shown in Fig. 4. Disposed between the uppermost and the lowermost coil are the intermediate coils 23. Each of these coils is also substantially elliptical in plan and at the ends each of on their inside faces as at 32, while the necks 31 are cut away on their outside faces. It will thus be seen that the necks 31 will fit within the ends of the necks 30 so that the ends of these necks will overlap. At alternate ends transverse webs or plates 33 are disposed extending across the necks 30, so as to form septums dividing one coil from another, in the manner well understood, so as to cause the water to circulate entirely around one coil before it passes into the next adjacent coil. These septurns 33 may be formed integral with the coil sections or disposed in place between the abutting ends of the necks 30 and 31. Preferably the coils have their side faces converging, though this, it is obvious, is a detail which may be modified to suit any particular design of coil. The coil 10 is provided in its length with a relief valve 34 to permit the escape of air until the coil sections are 'filled with water.

The coil sections may be held against each other in any suitable manner as, for instance, by bolts 35 passing through ears 36 formed upon the several sections, as is obvious from Fig. 1.

Having described our invention, what we claim is A radiator of the character described comprising a plurality of coils, including an'uppermost coil, a lowermost coil and a plurality of intermediate coils each having parallel longitudinally extending portions and transversely extending end portions, the intermediate coils each being formed at opposite ends with upwardly and downwardly projecting necks, the neck of one coil fitting into the neck of an adjacent coil, the topmost coil being formed with downwardly projecting necks and the lowermost coil being formed with upwardly projecting necks, the coils having septums disposed across said necks at alternate ends of the coils, to thereby cause the circulation of water entirely through one coil before passing into an adjacent coil.

In testimony whereof we hereunto afiix our signatures in the presence of two witnesses.
